    Abstract: Pure Tin Oxide (SnO2) and Magnesium (Mg) doped SnO2 thin films have been deposited onto glass substrates by spray pyrolysis technique at the substrate temperature of 450°C. The doping concentration of Mg was varied from 1 to 9 wt% (with 2 wt% step) while all other deposition parameters such as substrate temperature, spray rate, carrier gas pressure... Show More

    Abstract: The research was done to understand the influence of nano-sized donar dopant incorporation in barium titanate (BTO) structure. Core-shell structures are stated to form while dopants are added directly to BTO. Low diffusivity of ions in solid state results such core-shell structures. Pure BTO was doped with different concentration of niobium oxide (... Show More
